$1700 (Nikon) vs $900 (Sigma), I'll say! That is a huge difference in price. How many glass elements are in the Sigma vs the Nikon?

Sigma:
11 elements in 8 groups
The 85mm F1.4 EX DG HSM also contains one Special Low Dispersion (SLD) glass element (Sigma's version of ED glass) and a glass mold element to offer excellent correction for all types of aberrations and to ensure superior optical performance.
Nikon:
10 elements in 9 groups (with Nano Crystal Coat)
Apparently it doesn't have any aspherical elements or ED glass. BUT it doesn't suck because of it. AFAIK Nano coating does the same job as ED glass anyway right?! Nope, I just checked, it's to reduce flare, not CA. ED and Aspherical elements reduce CA etc.

So more doesn't mean better? It seems like a really close call, considering the Sigma is nearly have the cost. Would be nice to see side by side images taken with both lenses.

I remember reading about someone who tried both. He said the Nikon is a bit sharper, but the Sigma is close.
Here's some reviews:
www.lenstip.com/277.1-Lens_review-Sigma_...SM_Introduction.html
www.lenstip.com/264.1-Lens_review-Nikon_...4G_Introduction.html
and here are some borrowed (100% crop) samples from those reviews:
Sigma:
Nikon:
IMHO both are sharp enough for 1.4. I can't tell enough difference to warrant the price increase (YMMV).
Their summary of the Sigma review is worth noting:
We rarely publish uncompromising opinions in our summaries but here it would be difficult not to include one. Providing you own a Nikon or Sony reflex camera I personally don’t see any reason why you should buy any brand-name 1.4/85 lenses. The Sigma is cheaper, better and it comes with a longer guarantee – as simple as that. You must be really very infatuated with “Zeiss” or “Nikkor” magical words to prefer their lenses to the Sigma.

You guys are great, I'm going to give this a shot then. I'm no pro, so if I can save a few bucks, works for me!

That said, Sigma is capable of some real gems. I have the Sigma 70mm macro, and it optically out-performs the 100mm Canon Macro I used to have in every way. The only drawback is slower focusing, but I can live with that. I manual focus it anyway.
